Maybe you feel like you can't relate. But I think that if you consider carefully you will realize that even if you don't wear this mask that there are others you frequently don.
Perhaps its the mask of the "fake fine," the one you wear to try and convince everyone, including yourself, that everything is okay when it is not. Maybe it is the mask of independence & strength---used to convince those around you that you don't need them when inside you are crying for help. Maybe the mask is not just figurative---may be it is those layers of make-up (and I wear it, too) that you carefully apply daily to mask the blemishes, hide the fatigue, and somehow live up to someone else's expectations.
The reality that is that the Lord is pleading with us to remove the masks and throw them away. You see, when I breathed out "I hate this" as I got in my car and slammed the door I realized that the very thing that I hated (the mask) I was self-inflicting. I was frustrated by the fact that I felt like I needed the mask---I was alone (not an uncommon experience for an unmarried woman) and I was afraid. But then I realized that I was wearing the mask because I was believing a lie.---Because, the truth is, I am never alone (and I could never kick anyone's butt--my five foot four frame is just not build for that :). I am indwelt by the same God who "made the stars also." Jesus Christ, who is Lord of my life, came to the earth as Immanuel, "God with us" to suffer the awful separation from the Father for my sin so that I would never be alone.
No matter what mask you are wearing or what lie you are choosing to believe the Lord Jesus is asking you exchange the lie for His truth and to trust Him with your life and situation.
We are called to follow the truth: The One is the TRUTH says, "If you abide in My word, you are truly My disciples, and you will know the truth and the truth will set you free." John 8:31b& 32
